Abstract

Three separate safety trials and a comprehensive efficacy trial were conducted to demonstrate the safety and efficacy of FUSOGARD™ Fusobacterium necrophorum bacterin (ImmTech Biologics, Bucyrus, KS) for the aid in control of Footrot.

A trial was conducted to demonstrate the efficacy of Fusobacterium necrophorum bacterin against Footrot in calves when challenged with a virulent heterologous isolate of the bacteria. Calves were vaccinated twice, at day O and day 21. Each calf was challenged 14 days after the second vaccination with 0.5 mL of the virulent bacteria in the interdigital area near the coronary band. All control calves developed severe lameness, joint/soft tissue swelling and abscessation during the 19 days post challenge. Three of the vaccinated animals developed mild lameness.
